More Information
Summary:A powder of electrolytic manganese dioxide and a process for producing the same are disclosed. The powder has a maximum particle diameter of 100 µm or smaller, a content of 1 µm and smaller particles of lower than 15% by number, and a median diameter of from 20 to 60 µm, and which has a potential of 270 mV or higher in terms of the potential of a suspension of the powder in 40% aqueous KOH solution as measured using a mercury/mercury oxide reference electrode as a base.
